' vLettoniePatent No. 94,918, 'datefliS'eptember 14,'1'869.

The Schedulel referred to :ln these `Letters Patent and making part of the same.

'To all to whom 'it mayv concern v` Be it known that I, HENRY F. SHAW, of WestI Roxbury, countyofNorfolk, State of Massachusetts, have invented certain Impovementsin Gutters for Mowing-li'Iachines, of'which the following is e specification.

` Nature and Objects of the Invention. f

The subject' of' my present invention rela-tes to certain improvements" and additions to an invention for which I have applied for Letters Patent, said appli- .cation having `been liled August 19, 1869. Said impl'ovelnentsnnd additions cousistr First, oftlienddition oifan automatic clearing-de-- vice for removing any obstructing accumulations that may gather fin the rec'ess of the middle iinger, or of the finger or fingers which areliable to become clogged from the combinedA reciprocating motion of the two cutter-liars'. f i

Second, of.- the peculiar lform of construction of the above-mentioned finger; or fingers, with which the clearing-hook is combined and works. v

Description of the Accompanying Drawings. Figure 14v is'a perspective view of my invention. Figure 2 is a perspective view, showing in detail th'ejonts'ofthe pitmen, and cutterbars in line with the joint'upon which the finger-bar swings when elevated. f v

.Figure 3 shows inplan the centre inger and clearling-device. p

Figure 4, section .of the same. Figm'elfsllows, in plan, one-f the common fingers. .Figure'shows the same'in section.

Y' Geg'ze'raZ Description. l Y H represents thellcwer or stationary finger-bar.

D represents oiielhelf oi' the upper or vibrating cutting-bar, and is operated by the pitman D and crank B. O2, connected to the bar Ol, is the other half of the v vibrating cutter, and is operated by the pitman C and having been alredy described inv my former specica.-

`tion, it is not necessary to describe them more fully.

In fig. 2, I have shownthe-two pitmenfjoints in line with each other and with the joint F G, which connects the linger-barwiththe inside-shoeand to the other parts of thel machine, F being-en car attached to the finger-bar H, while G isa similar ear attached to the inside shoe, these two ears being joined together bya ypivot from the joint, there being asimilar device onthe other side ofthe iinger-bar.

In my device, it is necessary that all of these joints should be in line (or nearly so) at some point of the stroke, so that -the finger-barand cutters may be turned up when the machine Vis moving but not at work. or to clearobstructions.

In figs. 1, 3, and 4, P represents the middle finger, orthat linger that is opposite the point from which and to which the cutter-bars os'cillatc.

This Vlinger is made wider land larger other ways than the `other fingers, and is also provided witlran openingin its upperplate, as shown in iig. 3, between the points P' and l".

This upper plate P P'- P' is' alsorraised somewhat above the knives of the cutter-bar D', as shown in iig.

4, so that the clearer VK K' may pnss under it.

The clearerl K K' passes the finger P at each stroke, and thus'l prevents anysaccumulz'ttion of grass, &c., tha1 might clog the machine,

-In iigs. 5 nnd, I have represented somewhat in detail one ofthe common lingers of my mower.

L, iig. 1, is a balance-wheel attached to the crankshaft.

, I claim as my inventioning-machine, the clearing-hook'K K', or its equivalent, operating for the purpose set forth.'

2; Thel finger P P' P', made substantially as de scribed, in combination with the clearing-hook K K',

as and for the purpose set forth.
